Make sure you're sitting down.... this is one of the nicest amps I've ever seen in my life. I commissioned a good friend of mine (t h a n k y o u m y f r i e n d !!) for the cab & metalwork, and the results are spectacular. I installed my 1954 JBL D-130 speaker the night the cab arrived. Now for the electronics!

Wow! Very nice work!

I recently checked all hardware stores around for that aluminium strip (for carpets?) the same as on your amp, but could not find anymore... New DIY fashion?

I don't have this fetish, but I can say this schematic is quite possibly the most well designed guitar amp. Two chokes in the PSU? Everybody else is using one, even if that. And other niceties as well. Seems the guy was a perfectionist.

By the way telecastertech, the voltage does not divide itself that way. It is fed parallel to the screens, So they each get the full voltage. 100 or 470 Ohms will not have a great effect on the voltage but it will have effect on the tone, when driven hard.

I did take a look at that link you posted (thanks!) - and saw the Imperial cab with the 15" speaker in it. The postings threw me off a little bit because one guy said he had a Jensen P15 in there, but clearly, I see an aluminium dust cap so I'm thinking more JBL D-130. But after reading the rest, he mentions that the photo is of someone else's setup.

These cabinets were completed sealed in the back. The port for the low frequencies was open towards the front of the amp. Some people have reported great sound with these. Ampeg used to do this in the 60s as well with their Reflex Baffle system design. I am not aware that, in the Standel cabs, boards were installed on angles to 'channel' the sound, but clearly if a 'bass port' exists, something would have to help it along.

Really I'm just looking for "tried-and-true" plans or schemes for cabinetizing a D130(f). I have one from a friend who is looking for a "clean" guitar amp, and I know that he will want to gig with it, so I'm looking to take advantage of as efficient an application I can find that doesn't color the sound too much.

That front ported Imperial cabinet looked promising. Though I cited it as an example, my underlying motive is to use this speaker efficiently and "cleanly". Originally I was looking to power it with 18w (6v6 PP), but we are rethinking amplifiers at the moment.

Needless to say, the examples in this thread are beautiful and enticing! However we already have plenty of parts together that would constitute an amp but not a clone of the thread's namesake!

Anyway, thanks for the tip to look at Ampegs. If you know of any more information out there on this Standel Imperial design, I'd be interested in hearing about that as well. And, well, any advice you may have!
